You can do that by using fans other than the tiny, whiney, 40mm fans<br>
that vibrate at 6000 to 18,000 Hz. A couple of 80 or 120 mm muffin<br>
fans at the back or front, pushing air in (hence the deep<br>
dimensions), but the top and bottom would need recesses to allow<br>
sufficient airflow when the positions above and below are filled.<br>

How are you getting these 80 or 120mm fans in a 1U chassis? Remember
you got barely 45mm to play<br>
with at the back and front of the switch. How are you going to mount a
80mm or 120mm fan on there? Are you assuming that the units mounted<br>
above (or below) your switch is a short 1U? You can't assume that...<br>
